SYNCHRONOUS MOTOR RODMO 220V AC REVERSIBLE

Synchronous Motor is an electrical machine that moves keep in step with frequency and pole number, turns stable speed alternative current. While a synchronous machine working with turning electrical energy to mechanical energy, it will work as synchronous motor. It has the same design with synchronous generators. The direction of rotation of the ac synchronous motors can be determined by simply connecting a capacitor and a switch across the two windings as shown. The motors works at a fixed speed synchronous with mains frequency, at any torque up to the motor’s operating limit. They are also ideal for high accuracy fixed speed drives. The motors will speed up to operating speed in typically 100 milliseconds and will stop within typically 60 degrees once power is removed, depending on the load inertia. They are therefore suitable for positioning applications where the high accuracy of a stepper motor, for example, is not required If starting problems are experienced in applications featuring low friction torque it is usually because the load inertia is too high. In these cases a coupling with some compliance often helps to overcome this problem. When a gearhead is used for reduced speed operation the reflected load inertia at the motor is reduced by the square of the gear ratio.
